index

Please note that this is a work in progress; I've uploaded this draft mainly because I haven't found time to work on it over the past few months and want to make the information available sooner rather than later.  Specifically, I haven't yet filled in descriptions for some classifications that didn't have any entries until the mid-1910s.  These are marked below in red, and I hope to get to them soon.
